a
Responses ranged from 1 to 5, where 1 indicated the most stigma. Adjusted absolute changes were adjusted for respondent’s sex, race, education, employment status, and familiarity with alopecia areata.
b
Indicates that the variance among absolute changes among portrait race/sex categories was statistically significant (P ≤ .05).
c
No. for each mean myth Likert score is the total No. for medical condition for that corresponding portrait’s demographic and alopecia severity combination.
